NUT-LOCK.V

SPECIFICATION forming part of Letters Patent No. 258,873, dated June 6,1.882.

Application led September 24, 1881.

To all whom it may concern:

Be it known that I, SELDEN A. BAILEY, a citizen of the United States,residing at New York city, in the county of Westchester and State of New York, have invented certain new and useful Improvements inLockingWashers, of which the following is a specification, refer-4 encebeing had therein to theaccompanying drawings.

The object of this invention is to provide a washer of simpleconstruction which may be applied with facility, and which, when the nutis screwed up, will set perfectly tight upon the prop, bolt, or shaftupon which it is placed. A

washer of this sort is of especial importance in top-propsfor carriages,Where, it' the washer is allowed to move in the slightest degree, thenut soon becomes loosened and lost.

Vashers have heretofore been so constructed as to prevent theirrevolution on the shaft; but it has been found difficult to vsecure themrigidly thereto.

Figure l is a perspective view of this im-l proved washer. Fig. 2 is alongitudinal section on line 2 2 of Fig. 3 of a top-prop with thisimproved washer in position thereon. Fig. 3 is a transverse section ofthe same in line 3 3 of Fig. 2. Fig. et shows the washer placed inposition upon the prop, ready for the nut to be screwed down.

'lhe washer A is here shown in connection with top-props for carriages,being placed upon the prop B between the braces C and nut D. The washerA is a plain flat .annular metallic disk of the usual construction,except that it is provided with a short bent-up, square-ended,inwardly-projecting tongue, O. This tongue is formed by two parallelslits cut from the inner edge of the washer'about half-way through thesame. The inner edge of the washer, instead of being circularthroughout, is made straight on one side, and the slits are cut oneither side of the straight portion, so that the tongue (N0 model.)

sition the nut is screwed up, and the end of 5o the tongue is therebyforced down tightly and pinches against the fiat side of the prop orbolt, and the washer is rigidly locked to the shaft. These washers maybe made of steel or iron, and tempered, or not, and applied to variousforms of bolts or shafts.

Bolts, shafts, and props already in use may be easily adapted to thesewashers by simply attenng them on one side with a file.

What is claimed as the invention is 1. A metallic washer provided at itsinner edge with a short tongue formed by transverse slits cut in thebody ot' the washer,said tongue being adapted to open outward for theplacing ot' the washer and to close iiush under pressure of the nut, theend of the tongue being square or straight and adapted to bite firmlyagainst a iiattened portion of the bolt, shaft, or prop when pressedhome, substantially as described.

2. The combination of a prop, bolt, or shaft screw-threaded at one endand flattened on one side, a brace or other part on said prop, a nut forholding said brace, and a washer between the brace and nut provided witha short tongue the end of which bites firmly against the attened side ofthe prop as the nut is screwed home and holds the nut rigidly to theshaft, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

Witnesses:
